Abstract

Thirty-five genotypes of Mung bean (Vigna radiata L.) along with check Shalimar Mungbean-1 were evaluated to elicit information on association and interrelationship for yield and its component traits. Seed yield plant-1 showed positive significant association with number of clusters plant-1, number of primary branches plant-1, number of pods plant-1, number of seeds pod-1, pod length, and 100-Seed weight ,and  negative and significant association with days to 80 % maturity. Path analysis revealed that maximum positive direct contribution to seed yield plant-1 came from number of seeds pod-1 (0.424) followed by 100-Seed weight (0.419, number of pods plant-1 (0.339) and number of primary branches plant-1 (0.177). Significant positive indirect contribution came from all the traits via pod length and number of seeds pod-1. None of the genotypes showed complete resistance to cercospora leaf spot (CLS) however 17 genotypes were rated as moderate tolerant and 15 as moderately susceptible.

Key words:  Mung bean, correlation, path-coefficient, Cercospora leaf spot.
